In a motor drive control system configured to include a converter capable of stepping up the voltage, when the locked state of MG2 operating as an electric motor does not occur (NO in S130), a voltage command value VHref for the converter output voltage is set according to respective required voltages of MG1 operating as an electric generator and MG2 (S140). In contrast, when the locked state of MG2 occurs (YES in S130), the voltage command value VHref is set to a limit voltage Vlmt or less for limiting the voltage step-up by the converter (S150, S180). When the locked state occurs, the converter output voltage is decreased and accordingly the DC voltage switched by the inverter is lowered, so that a switching loss at the switching device forming a part of the inverter is reduced and the temperature increase due to the heat generation can be suppressed.

The gas turbines of the present invention have multiple combustion chambers, and within each chamber are multiple fuel nozzles. Each nozzle has its own fuel control valve to control the fuel flowing to the nozzles. To minimize the pressure drop through the fuel control valves, multiple manifolds are employed. Each manifold supplies at least one fuel nozzle in multiple combustion chambers with fuel. The fuel control valves are mounted on the manifolds such that the weight of the fuel control valves and nozzles are carried by the manifolds, not the multiple combustion chambers. A plurality of thermocouples for measuring exhaust gas from said multiple combustion chambers are employed to sense gas exhaust temperature. In carrying out the methods of the present invention for tuning a gas turbine, it is essential to note that the most efficient gas turbine is one which has the least nitrous oxides, the least amount of unburned hydrocarbons, and the least amount of carbon monoxide for a specified energy output. In order to tune the gas turbine to accomplish these objectives, it is desirable that each combustion chamber in the gas turbine be well balanced relative to the remaining combustion chambers. It is an aim of the present invention to tune each of the multiple combustion chambers such that no specific combustion chamber is rich or lean, and all are operating within about 1% of the remaining combustion chambers.

A mobile terminal includes a channel estimation processor to obtain the channel estimation value of a first channel reception signal in use of a plurality of known signals received from a base station within a channel estimation period; a channel compensation processor to perform a compensation process of the first channel reception signal in use of the channel estimation value; and a controller to control the channel estimation period so as to use a known signal which is received after the reception of the first channel reception signal for channel compensation. With this, throughput in downlink communication can be improved by controlling the deterioration of HS-SCCH reception quality itself without any particular transmission power control with the base station even under an environment such as high speed fading.

A signal pair interference power ratio of the received signal at a user terminal is obtained and this ratio is then compared with the signal pair interference power ratio required for correct demodulation. Accordingly, the user terminals can be classified into those in the non-interference domain and those in the interference domain. A plurality of access points make the simultaneous communications to the user terminals in the non-interference domain and also make the communications on the time-division basis to the user terminals in the interference domain. Thereby, it is now possible to solve the problem, in the communication system in which the total throughput of the system can be improved through simultaneous transmissions from a plurality of access points with the wireless access system to connect the user terminals to the wired network via the access points, that the throughput of the user terminal which cannot demodulate correctly the desired signal if the data packets collide with each other is more deteriorated than the user terminal which can correctly demodulate the desired signal because the desired signal pair interference power ratio is large even when the data packets collide with each other.

An AC servo drive without current sensor includes a PI (proportional integration) controller, at least two first-order controllers (polar point and zero point), a decoupling compensator, a coordinate converter, a pulse width modulator, a counter and a speed estimator. The AC servo drive is connected with a servomotor to form an AC servo module. The servomotor comprises an encoder receiving a current command signal from the servo module to function as input current command signal or the d, q axes PI controller and the decoupling compensator. The voltage command signal generated by the d, q axes PI controller and the signal generated by the decoupling compensator form a control signal and input to the coordinate converter. The signal output from the coordinate converter is processed by PWM controller to control the servomotor. Therefore, the deterioration of servo motor control caused by temperature drift and cost can be solved.

In a motor control device controlling a motor by a state feedback control, high control accuracy is maintained regardless of fluctuations in a motor load so as to improve control performance of the state feedback control. A control signal (manipulation amount) outputted from a feedback calculator for controlling the motor is compared to a manipulation threshold set to a manipulation threshold setting register so as to determine the magnitude of a load amount of the motor. The feedback calculator includes an observer and performs the state feedback control of the motor. When the load amount is in normal level, a normal load observer matrix set in an observer table is selected to configure a normal load observer. When the load amount is increased, a high load observer matrix is selected to configure a high load observer.

A converter converts input signals to digital values at a conversion cycle shorter than a cycle of the input signals. A data storage device sequentially stores digital values obtained from the converter, and a processor calculates a mean value to fetch the stored digital values for a cycle time of the input signals, and computes an arithmetic mean of the fetched digital values for target control purposes.
